20.500.12556/RUL-115090 Rast smreke in bukve na strmih legah v Bohinju diplomsko delo - visokošolski strokovni študij - 1. stopnja The growth of spruce and beech on the steep slopes in Bohinj V diplomski nalogi je analizirana rast smreke (Picea abies) in bukve (Fagus sylvatica) na strmih legah v Bohinju. Smreke in bukve so bile izbrane na različnih naklonih, nadmorskih višinah ter legah. Skupaj je bilo analiziranih 60 dreves smreke in 60 dreves bukve, ki so se uvrščale zlasti v vladajočo ali sovladajočo plast sestojev. Na vsakem drevesu sta bila odvzeta dva izvrtka, in sicer na panju ter na prsni višini (1,3 m od tal). Smreka je ob nižji povprečni starosti dosegala višje višine kot bukev. Povprečni debelinski in višinski prirastki smreke so bili večji v primerjavi z bukvijo. Na priraščanje je v največji meri vplivala starost drevja. Sproščene smreke so imele širše branike, bukve pa ne. Odvisnost širin branik od klimatskih spremenljivk je bila praviloma statististično neznačilna, nekoliko v tem pogledu izstopajo avgustovske temperature. In this work the growth of Norway spruce (Picea abies) and European beech (Fagus sylvatica) on steep slopes in Bohinj was analysed. Spruce and beech tree were selected at different inclinations, elavations and aspects. In total, 60 spruce trees and 60 beech trees mostly of dominant and co-dominant social layer were analysed. On each tree two increment cores were taken, on the stump and at the breast height (1,3 meter above ground). The spruce trees were on average higher and a bit younger. Average diameter and height increments of beech were lower in comparison with spruce. The strongest effecton growth rates had tree age. Spruce trees with released crowns had wider tree-rings, what does not hold true for beech trees. The dependence of tree-ring width on climate variables was mainly statistically nonsignificant, with the small exception of August temperatures. debelinska rast višinska rast smreka Picea abies bukev Fagus sylvatica skrajna rastišča Bohinj true false false [M.
